How to use the Trucking Cost Per Mile Calculator
Enter your monthly miles and the share of them that are deadhead (empty).
Add fixed costs: truck and trailer payments, insurance, permits and software, all per month.
Add variable costs: diesel price and MPG, maintenance and tire reserve per mile, tolls and any hired driver pay.
Set your income goal and an optional profit margin, plus the rate you are being offered.
Press Calculate cost per mile to see cost per mile, break-even rate, target rate and the full breakdown.
Trucking cost per mile formulas
Cost per mile = (fixed costs + variable costs) ÷ total miles
Fuel cost per mile = diesel price ÷ MPG (for example $3.75 ÷ 6.5 = $0.577)
Loaded miles = total miles × (1 − deadhead %)
Break-even rate per loaded mile = total costs ÷ loaded miles
Target rate = (total costs + income goal) ÷ (1 − margin %) ÷ loaded miles
Example: a truck runs 10,000 miles a month with 12% deadhead. Fixed costs are $4,500 and variable costs are $8,119 (fuel $5,769, maintenance $1,800, tires $400, tolls $150, no hired driver), so the total is $12,619. Cost per mile is $12,619 ÷ 10,000 = $1.262. Only 8,800 miles are paid, so the break-even rate is $12,619 ÷ 8,800 = $1.434 per loaded mile.

Tips to lower your cost per mile
Cut deadhead first. Every empty mile adds cost with no revenue; planning backhauls often helps more than chasing a slightly higher rate.
Watch idle time and speed. Fuel is usually the biggest single cost, and a lower cruising speed can improve MPG noticeably.
Shop insurance every renewal and keep a clean safety record, since insurance is one of the largest fixed costs.
Recalculate monthly. Diesel prices, miles and repairs change; a cost per mile from last year can hide a loss today.
Frequently asked questions
How do you calculate cost per mile for a truck?
Add up every cost for a period, both fixed (truck and trailer payments, insurance, permits) and variable (fuel, maintenance, tires, tolls, driver pay), then divide by the total miles driven in that period. For example, $13,000 of monthly costs over 10,000 miles is $1.30 per mile.
What is the difference between cost per mile and cost per loaded mile?
Cost per mile spreads costs over every mile the truck drives. Brokers and shippers only pay for loaded miles, so your break-even rate must cover the empty miles too: divide total costs by loaded miles. With 12% deadhead, a $1.30 cost per mile becomes about $1.48 per loaded mile.
What is a typical owner-operator cost per mile?
It varies widely with equipment age, insurance, fuel prices and miles driven. Industry surveys such as ATRI's annual Operational Costs of Trucking report have put total marginal costs roughly in the $1.80 to $2.30 per mile range in recent years, including driver wages and benefits. Your own records are the only reliable number, which is why this calculator uses yours.
Why does my cost per mile go down when I drive more miles?
Fixed costs like the truck payment and insurance stay the same each month no matter how far you drive. More miles spread them thinner, so fixed cost per mile falls while fuel and maintenance per mile stay about the same. The mileage table shows this effect for your numbers.
Should I include my own pay in cost per mile?
Many owner-operators keep two numbers: the operating cost per mile without their own pay (the true break-even for the truck) and a target rate that adds their income goal. This calculator does exactly that, and you can add a hired driver's per-mile pay as an operating cost.
How much should I set aside for maintenance?
A common rule of thumb is around 15 to 20 cents per mile for maintenance and repairs on a mid-age tractor, plus a few cents per mile for tires. Older trucks and heavy-haul work need more. Put the money in a separate account so a major repair does not stop the business.
Does the rate per loaded mile include the fuel surcharge?
Compare like with like. If your costs include all fuel, compare them against your all-in rate (line-haul plus fuel surcharge). Our Fuel Surcharge Calculator works out the surcharge part from the diesel price.
